Just bought your M3's for family room. Only problem is that they make my living room speakers sound like crap! Therefore I need (want)new ones for the living room (18 feet x 10 feet, open concept house). Amp is 85 watts/channel. Is this adequate for M50, M60, M80's? (Haven't decided which I like best yet) I don't play music at really high volumes.

85 watts a channel is just fine for the M50, M60 and M80. The only thing to watch with the M80s is that you can process 4 ohms, rather than the standard 8. We run the M80s in an 'open concept' house as well, with great success. Having said that, the M60s sure get a lot of fan mail!
